Trigger Pull: Fairly short with only a little bit of take up. The release is light and crisp. The blowback action resets the internal hammer/striker with each shot for that true single-action trigger. It’s also nice that the trigger has a working trigger safety.

Accuracy: I placed 10 shots into a paper target with my Umarex Glock from a distance of 30 feet down range using my standard seated and rested shooting position (sand bag up front and sitting in the back). Shots did spread out a bit, getting close to a 4 inch group but I think some of this had to do with the fact that I was still using the lighter weight .20 gram airsoft BBs. Heavier .30+ gram airsoft BBs may have produced a tighter grouping for me. Even so, 4 inches at 30 feet that were pretty well-centered is good enough for close quarters shooting which is what an airsoft pistol is meant for.

Build Quality: The Umarex Glock 17 4th Gen seems well-made overall. It does seem a little bit underweight but it still feels solid enough in the hand. The slide is metal but has a bit of an unusual finish that makes it look a lot like a plastic frame rather than a more shiny metal look. All the parts seem to fit nicely, maybe even a bit snug at first, as I noticed the side had a bit of friction to it but seems to be working in nicely now.

Realism: The Umarex Glock 17 4th Gen GBB Airsoft Pistol looks the part of a Glock 17 4th Generation all day long. Other then the slightly lighter weight it would be hard to tell off hand until you remove the magazine and take a closer look. All the parts work as you would expect them to, similar to the real steel version. You can even fully field strip the pistol which makes getting to and adjusting the hop-up easy enough to do.

Pros:

1:1 scale replica of the Glock 17 with official licensing

Ergonomic 4th generation grip

Realistic gas blowback action

Adjustable hop up system

Full sized metal drop out magazine

Cons:

Orange tip detracts from realism

Sights are not adjustable

Comments: At long last, Umarex has delivered an officially licensed GLOCK airsoft pistol replica. The GLOCK 17 Gen 4 is functionally identical to the real steel firearm that inspires it. Shooters will love the familiar ergonomics, take down procedure, metal slide, drop free 20 round magazine, and the realistic blowback action. Other features include fixed white dot sights, a functional trigger safety, and a tactical rail for flashlight mounts or laser sights.

I wasn’t sure if I was going to get my hands on one of the Umarex Glock 17 4th Gen GBB Airsoft Pistols since the velocity was a bit low for Canada import but somehow we managed to squeak some in to our Replica Airguns Canada Store and for me to get a review out for everyone!. In this video we see how well Umarex’s Gas Blowback Glock 17 Gen 4 performs in the Replica Airguns Indoor See Can Shooting Range. I test out the velocity and accuracy and also talk a little bit about how the gun performed overall for me. And yes I have already made a Table Top Review Video so if you want those closeup shots and specifications then watch that video too…

Starting off with my velocity power test using my Caldwell Ballistic Precision Chronograph and using .20 gram Airsoft BB’s with a full magazine of propane gas, I hit an average of 283 fps with the fastest shot getting 289 and the lowest shot hitting 279 so only a 10 fps difference. Shooting conditions where decent in the See Can, a lot warmer than outside but still not as warm as your typical summer day. The temperature was 15 Degrees Celsius (59 Degrees Fahrenheit). In warmer conditions I am sure I would have hit closer to 300 or even high fps with the Umarex Glock 17 4th Gen GBB Airsoft Pistol.

Cons:-May or may not come with an orange top but can be fairly remissly removed.-Sight are non-adjustable which is common with low cost airguns like this one.-FPS is a bit low making Canada import difficult.
